Clinical studies have shown that Liuwei Dihuang pill (LWDH) can effectively increase GFR (P < .05) and reduce the ratio of urinary albumin to creatinine (P < .05) in patients with CKD.[12] Furthermore, another study found that patients with CKD who used LWDH as adjuvant therapy exhibited a lower incidence of ischemic stroke (P < .05). Here, ALB is linked to chronic kidney disease.
